TERsoN, a citizen-'oli'. the

United States, residingsr` 'et Krebs, in the county 'of Pittsburg and State of Oklahorne, have invented new and usefull improvements in Mine- Car of ywhich the following is c specilication. f f

This linvention relates to mine andthe objectsv of thesame are to labor and cost-of vcasting; mine cur Wheels,

Wheels; to the central portion ofthe' Wheel adjacent to the aigle and tofirnpeseall'the Weir'upon and provide for Ythereplacement ofv interposed bearing devicesbetween the Wheel and axle; to .render ythe-rotution Aof the-wheel easy by the instellation` of anti-rictional devices between the Wheel proper and the axle, and also to equip this type of Wheel with a self-lubricating-means which Will, have a lasting operaf tion gV to 'provides mine Wheel with inner andoute'r dust-proof'--structures or components-'that Will also prevent back thrust of the and protect the latter; .and to the @Wheel lfrein the outside.

Witli these and other objects and edvanteges in View', lthe invention consists in --thef-construction end arrangement of the several parts which will ybe more fully here y' inaffter 'I described and claimed In 'fthe drawing Figurefjl lis t perspective View of the improved mine car wheel and e portion oi .its

end at the saine time sary strength thereof, pleted by ybfning the opposite ends, as at 6, to provide i-:ey pin pockets or seats. The Wheel 7 is cast-from suitable metal and comprises en outer iienged rim 8 und an enlarged central bore 9 to loosely and roti-rtv f ably lit over 'what may be termed a non rotatable hub organization embcdyingscparable and replaceable components in which the seid axle 5 is centrally disposed. The oily Wear on the wheel 7 occurs at the flanged rim S which engages the track rails,` andthis Wear is reduced to i minimum. By thus conetmeeting the Wheel proper it can be cheaply manufactured and will be strong and durable in its service.

The hub organization comprises essentially an cuter' steel bushing or sleeve 10, n boi; .il with :i central square. bore l2 in which the axle 5 is ,ttcd, and en inner steel ibusliing or sleeve iitted over the router surface oi' the boit il, anti-frictional `rollers or analogous devices 14 being introduced between the bushings or sleeves l0 and '13 and serving to girovide an easy running Wheel. The bex l1 is kformed With a circumferential oil chamber or groove 15 having c strip 16 of felt inserted therein and disposed throughout the interior of the chamber. An openingor iced port ll' is formed in" the box ll. in communication With the vchamber 15 preservethe neces-y the axle bemg coinistering with the 'opening or'po'rt 1'? of the box ll to permit the oil or lubricant to run into or be supplied to the space between the bushings l0v and l'and to the anti-frictioncl rollers 14. It will be seen that the Wheel 7 is provided with un untiifrictilonel oiled or lubricated bearing4 havin resist wear, und that al cci Y. of llieiiclt or other strip 16, cant is regularly and economically supplied to the wheel beau-ing by capillary action, and the chamber l5 muy be charged roni'the outer side ofthe wheel with a, quantity'of oil or lubricunt that will lost for several months without replenishment, particularly in View ot' ilul economical dispensation othe oil troni the I hard'busliings to,-

weer is Arelieved i from the wheel proper and the boitv or hub' all.. Moreover, through the mediumv the oil or lubrichamber by means heretofore speci;

fied. It will also be noted that the oil chamthrust of the rollers ,14, said ring having an offset 21 which projects into the wheel bef tween the bushings 10 and 15 and serves to keep dust. out of the wheel bearing. The bushing 13 also has a rear or inner annular flange 22 with an opening 23 therein, and surrounding and fixed to the inner end of the box 11 is a flange 24 having a dowel pin 25, the flange 22 removably bearing against the flange 24 with the pin 25 fitting in the opening 23. The flanges 22 and 24.

close over the rear or inner portion of .the bore 9 of the wheel and form a dust guard at this point and also resist or take care of the back thrust of the rollers 14. The wheel and bearing components together with the ring 20 are held in removable operative association on the axle extremity by a lpin 26 inserted in the opening 5 and through the'axle extremity and bearing against the outer portions of the box 11 and ring 20,y

The mine ear Wheel constructed as above explained and embodying the features of the invention has many advantages relatively to mine oar Wheels now in use. In the improved wheel there'is no possibility of the rollers 14 by wear embedding-themselves in the' body of the Wheel, and as said rollers are held between hard surfaces the wheel yvill be maintained in truc and free running condition, and if the bushings or sleeves 10 and 13l become worn they may he easily replaced and the working life of the wheel thereby prolonged at a small expense. By constructingv or casting the oil box 11 separately from the wheel, the entire wheel is not crippled or rendered unfit for use in the event that the said box break down as a re sult of excessive strain, sudden stoppage and -wrecks, and, furthermore, the inconveniences and losses incidental to casting an oil box as an integral part of the wheel are avoided. The improved wheel has inside means to withstand sudden thrusts when the wheel makes sudden turns or curves, provided by the flanges 22 and 24 next to the axle 5, and the outside ring 20 prevents outer thrust. Usually, the Wheels on mining cars in going around curves of tracks which are not graded to take care of the centripetal force of the cars are caused to Wear unevenly either at the extreme inside or extreme outside and thereby set up great friction and have to be discarded. The improved wheel herein disclosed overcomes these latter disadvantages through the resisting means provided to lobviate this inner and outer wear. The parts vor components of the hub or bearin for the improved wheel will be standardized and proportioned to various sizes'of wheels so that they may be readily procured from a manufactureror mine stock dealer andI quickly' substituted for worn parts or com onentsl that haveA to be discarded -with evi ent advantages in keeping mine cars in a practical running condition without requiring 4'ex-V tensive delay inthe use of the `cars -for the purposes of repair.

In the construction shown by Fig. 4 the essential features of the improved wheel are preserved and the same reference characters are used, the anti-frictional rollers 14 being omitted. In this form of the wheel the two bushings or sleeves 10 and 13 are contiguous, or, one bears on the other. In this form of the wheel the same advantages are resident as in the preferred form first described, except that the wheel will not run quite as freely in view of theabsence of the anti-frictional devices or rollers 14.

A mine car wheel comprising a fixed hub organization with a central 'box formed with a circumferential chamber having a textile lubricant absorbent therein and extending therearound and also havingabushing removably mounted thereon with an opening therethrough, a wheel having a bore with a bushing removably applied therein and rotatably mounted over the bushing of the box, and an axle angular in cross-section inserted and secured in the center of the box.

4. A mine car wheel comprising a fixed hub organization with a central box having a bushing removably mounted thereon, a Wheel having a bore with a bushing removably applied therein andA rotatably mounted over the bushing of the box, anti-frictionalV l devices between the two bushings, a dust and thrust guard means at the inner side of the wheehoan outer dust guard and thrust ring,'disposed to have ay portion thereof exosed between the bushings for engagement y the ends of the anti-frictional devices, and an axle an lar in cross-section inserted and secured in the center of the box.

5. A mine car Wheel' 'comprising an axle, acenter box mounted on the axle and held against rotation, a. mounted on the said box, a wheel structure independent of vand provided/ with a bore having a bushing Iremovably applied therein and rotatably mounted over the bushing of the box, the box having lubricant carrying and supply means, and an outer dust guard and thrust 'ring to. take up Wear and disposed to engage the box and; car Wheel and laving a portion thereof exposed between 1the bushings and .to engage the ends of the atter.
